Faulty articulation of cleft palate speech due to velopharyngeal incompetence can now be defined not only on an auditory basis but more precisely on the basis of the dynamics of the articulatory organs with the use of nasopharyngofiberscopy and videofluoroscopy. In the process of our clinical research, we found 17 patients who had abnormal constriction of the larynx among 42 patients with glottal stop production.The constriction, related tog lottal stop on plosive consonants resulted from adduction of the arytenoids, medial movement of the aryepiglottic folds, and backward movement of the epiglottal base leading to approximation or even contact between the arytenoids and epiglottal base.Abnormal laryngeal constriction appears to be closely related to glottal stop.
